J UDSON ALLEN, OF EVERETT, ASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM H.OROTSER, OF AUSTIN, MISSOURI.

IMPROVEMENT IN FRUIT-DRIERS.

Specification forming part of Letters Patent No. 117,029, dated July 18,1871.

To all whom it may concern:

Be it known that I. J UDsoN ALLEN, of Everett, in the county of Cass andState of Missouri, have invented a new and Improved Fruit-Drier; andI dohereby declare that the i'ollowin gis a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being' had to the accompanying drawingforming part of this specification.

This invention relates to improvements in fruitdriers; and it consistsin a novel arrangement of a heater, hot-air-conducting pipes, andfruitdrawers, in a wooden case having a heat-generating compartment, andanother for distributing the heat over the fruit contained in thedrawers, all as hereinafter described.

Figure 1 is a sectional elevation of myY improved drier taken on theline a' .r of Fig. 3. Fig. 2 is a section on the line y y of Fig. 2, andFig. 3 is a horizontal section.

Similar letters of reference indicate corresponding parts.

A is a strong closely-made wooden case, having two compartments, B andC, divided horizontally by a partition, D. YVThe lower one, O, is linedwith thin sheet metal, and has a heat-generating stove or cylinder, F,having an inclosingjacket, G. The upper compartment is nearly filledwith fruit-holding drawers H, one above another, and drawing out of thecase on two opposite sides alternately. The drawers are intended to havethe bottoms formed of thin pieces of wood, set on edge at suitabledistances apart, to admit a 'ee circulation of the heat. The smoke-pipeI rises up at the side from the rear end of the heater, between thedrawer-supports lk and the side of the case, to the space above theupper drawer, and extends over it to the center,

where it passes out through-the roof. A hot-air pipe, L, rises up at theother side of the case to the top of the second drawer from the top, andis coiled around the case thereat to impart its heat to this and theupper drawer. M represents a pipe rising up in each corner of the casefrom the compartment O, one of which is arranged with each of theremaining drawers below the second drawer from the top in the same waythat pipe L is, the whole arrangement of smoke and heatin g-pipes beingsuch that the heat will be distributed in the most equal and uniformmanner.l All the hot-air-conducting pipes are to have small perforationsto allow the air to escape into chamber B containing the drawers. Nrepresents two tubes or air-passages extending through the case fromside to side at the center in the partition D for admitting cold air toprevent the drier from being heated up too much; said passages havedampers'for regulating thev amount of air admitted. All the hot-airpipes, as well as the smoke-pipe, will have dampers for regulating theheat. The wood case is employed in preference to any other on account ofthe heat-retaining qualities of the wood.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The wooden fruit-drier case, containing the heater ina metal inner compartment, C, and the drawers in the compartment Babove, and having the hot-air pipes, the smoke-pipe, and the cold-airpipes N, all arranged substantially as specied.

J UDSON ALLEN.
